Doesn't seem to have been many ST tire failures this year.

I forget, I am running something like 205-70-14's on my travel trailer. I do 55 to 58 mph, and always top off the pressure to 55 psi as stated in the instructions. I am at 14,000 miles in 2 years of ownership. So far, so good, but I am checking the tires like a hawk now, every time, before every trip, for signs of delamination.

Maybe this isn't such a problem with 3700 # dry weight ultralite travel trailers?
